BNG for home builders
Government's Biodiversity Net Gain (BNG) mandate came into force for major sites in 2024, requiring a minimum of 10% BNG on new developments in England. We are working with members and stakeholders to develop BNG guidance, and capture feedback that supports ongoing improvements.

How we are representing our members
The Government is continuing its engagement with the development industry as mandatory biodiversity net gain (BNG) beds in. HBF has a key role to play in collecting and sharing feedback from members on what is working and what isn’t.
In the lead up to the mandate's introduction, HBF was a key member of the Future Homes Hub BNG preparedness group helping to shape the implementation of BNG policy as it was being brought in.
HBF supported the principal of BNG and recognises the role that new development can and should play in helping to address the nature crisis. However, the implementation of the policies and processes to deliver BNG however must not prevent the delivery of much needed homes, as to do so would undermine the Government’s growth agenda and commitment to 1.5 million new homes within this Parliament.
Now that Mandatory BNG is in place, we to feed into BNG policy and practice. We remain a key member of the FHH BNG Implementation Board and Community of Practice.
HBF member group
Our BNG Working Group meets virtually every quarter to discuss BNG updates and gather feedback on its implementation.

LoginIs BNG policy changing?
The Government recently consulted on potential changes to BNG for small and medium sites.
The consultation documents are available here (link) and the HBF response here (link).
The thresholds at which BNG requirements apply is one of the key questions of the consultation.
We have been informed that the Government will be considering the consultation responses received over the summer and preparing something for ministers to consider in ‘the autumn’.
We were also advised some of the changes proposed require secondary legislation, so there won’t be any changes to the policy in the short term.
We were also old there will be a ‘transition period’.
We have requested an official statement about the timeframe, as we are aware that the uncertainty was already causing issues.
We will notify members of any changes/updates as soon as we have them.
